UNITED STATES PATENT OFFICE.

LEE F. FRANKLIN, OF KANSAS CITY, MISSOURI, ASSIGNOR 0F ONE-HALF TO GLAD'YS I SMITH. OF KANSAS CITY, MISSOURI.

WASHING MACHINE.

Application filed September 4, 1923.

To all whom it may concern:

Be it known that I, LEE F. FRANKLIN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in \Vashing Machines, of which the following is a specification.

My invention relates toimprovements in washing machines.

One of the objects of my invention is to provide a novel washing machine, which is simple, cheap to make, durable, not liable to get out of order, which is easy to operate and which is efiicient in operation.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred embodiment of my invention,

Fig. 1 is a side elevation of my improved washing machine.

Fig. 2 is a top view of the same.

Fig. 3 is a longitudinal sectional view on the line 33 of Fig. 2.

Fig. 4: is a horizontal sectional view on the line 4 .1. of Fig. 3.

Fig. 5 is a vertical sectional view on the line 55 of Fig. .1.

Similar reference characters designate similar parts in the different views.

1 designates a tub which is preferably rectangular and the body of which is preferably wood, and which may be provided with legs 2.

The bottom of the tub 1 may have a drain opening normally closed by a removable plug 3.

In the tub and below the normal. water level is disposed a horizontal wash board which may consist of a flat horizontal board l, the upper surface of which may be covered with a zinc plate 5 having formed therein horizontal transverse parallel corrugations 6, against the upper surface of which the clothes to be washed are forced lengthwise of the tub and transversely to the corrugations 6 by means of parallel corrugated rollers, disposed above the plate 5 and adjacent thereto and designated by 7. The rollers 7 have peripheral longitudinal corrugations parallel with the corrugations 6. The rollers 7 are respective y r g d y se- Serial No. 660,733.

cured to horizontal transverse shafts 8 disposed in the same horizontal plane parallel with each other and having their rear set of ends rotatably mounted in recesses provided therefor in a horizontal plate 9 which is secured to the inner side of the rear side of the tub. As shown in Figs. 2 and 5, the inner side of the front portion of the tub 1 has secured to it a horizontal plate =10, through which extend the shafts 8 and in which said shafts are rotatable. For preventing leakage, through the plate 10, each shaft may have mounted on it a packing collar 11, disposed outside of the tub and having threaded engagement with the plate 10, against which it presses packing 12, which encircles the adjacent shaft 8.

Intermediate of the rollers 7, and parallel therewith and in the same horizontal plane, are rollers 18, having radially extending peripheral bristles 14, which are adapted to rub against the clothes as the latter pass between the rollers 8 and the corrugated plate 5. The rollers 13 are rigidly secured respectively to horizontal shafts 15, which are mounted rotatably in the plates 9 and 10, in a manner corresponding to the mounting of the shafts Stherein.

In the drawings, there are shown thre'e rollers 7 and three shafts 8 and two rollers 13 and two shafts 15.

For. holding the corrugated plate 5 of the wash board by resilient pressure in its operative position, the wash board has secured to the under side of the board 4: four vertical pins 16, which are vertically slidably mounted in suitable guiding supporting means consisting of a horizontal board 17, disposed in the tub 1 and having four vertical holes in which the pins 16 are vertically slidable.

Respectively encircling the pins 16 are four coiled springs 18, the lower ends of which bear against the top of the board 17, and the upper ends of which support the board 4. The springs 18 serve to hold the wash board with resilient pressure against the clothes.

Supporting the board 17 are four tubes 19, the lower ends of which rest on the upper side of the bottom of the tub 1, and through which respectively extend four vertical bolts 20. whi h lso e tend. th h the be and and through the bottom of the tub and have their heads resting on the top of the board 17 andtheir lower ends provided with nuts 21, which bear against the under side of the tub. I

For revolving the rollers 7 and 13 all in a like direction, the outer ends of the shafts 8 and 15 have respectively secured to them spur gear wheels 22. Intermediate spur gear wheels 23 respectively mesh with adjacent pairs of gears 22- and are respectively mounted on studs 24 which are secured to and extend outwardly from the front side of the tub l.

Rigidly secured to the center shaft 8 is a large spur gear wheel 25 which meshes with a pinion 26, which is rigidly secured to a horizontal shaft 27 rotatably mounted in a bracket 28 which is secured to the front side of the tub 1.

For manually rotating the shaft 27, it has securedto it a crank 29.

For rotating the shaft 27 by power, the shaft has secured to it a pulley 80 adapted to be connected by a belt, not shown, with any suitable motor.

In the operation of my invention, if the shaft 27 is rotated clockwise, Fig. 1, the rollers 7 and 13 will be rotated counterclockwise and will force clothes to be washed to-the right, as viewed in Figs. 2 and 3, between the corrugations 6 and the rollers 7 and 13. If the tub is filled with soapy water, the clothes will be rubbed by the rollers 7 against the corrugations 6 and the bristles 1 1 will rub against the clothes. The clothes may be passed a few times between the rollers and the washboard, which will clean them, after which they may be rinsed by substituting clear water for the soapy water and passing the clothes between the wash board and the rollers in the manner already described. 7

The board 17, tubes 19 and springs 18 serve as resilient supporting and guiding means for the wash board, whereby the clothes are held with a yielding pressure against the rollers.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made Without departing from the spirit of my invention.

What I claim is:-

1. In a washing machine, a tub, a horizontal guiding board having vertical holes therethrough, means for supporting the guiding board in the tub spaced apart from the bottom of the latter, a washboard above said guiding board provided with vertical downwardly extending pins vertically slidable in the holes of the guiding board, horizontal rollers rotatably mounted in the tub above and adapted to co-operate with said washboard, means for rotating said rollers, and coil springs encircling said pins and supported by the guiding board and supporting said washboard.

2. In a washing machine, a tub, a horizontal guiding board in said tub, spacing tubes supported by the bottom of the tub and supporting said guiding board, the latter having vertical holes therethrough, bolts extending through said tubes and connected with the bottom of the tub and with the guiding board for holding-the latter in operative position, a washboard above the guiding board having downwardly extending pins vertically slidable in said holes, resilient means for normally forcing the washboard upwardly supported by said guiding board, horizontal rollers rotatable in said tub above and co-operating with said washboard, and means for rotating said rollers.

In testimony whereof I have signed my name to this specification.
